Hi,
I am doing the extracted simulation for the limiting RX, please refer to the attached document (schematic layout and plots) and help to think about what would cause this performance degradation?
fig3 is the AC magnitude response after TIA, Limiting amp, and output buffer, the results are got from individual extracted cells by using config in Cadence simulation.
fig4 is the same plot for the overall extracted simulation.
actually the metal connection between each blocks are not very long. any ideas about this?
thanks for your time!
